This girl that i like does drugs

Well we have liked eachother since 7th grade right? Well now she is single, but see she is under a lot of stress, and is smoking weed a lot again, well I used to do drugs all the time so that usually wouldnt be a big deal, but now I'm a huge christian...

and if we were to date then I'm pretty sure I would get back into drugs, but we really like eachother too, if you dont understand what it means to be a christian, then dont answer this question, and dont say if she really liked you then she would stop because I wouldnt make her choose like that

Like I told you on your other question -
Show her a better life, but the sounds of it she's under a lot of stress and that's what is making her smoke weed. If you show her fun that doesn't involve drugs and hang out with her to get her mind off it, she'll realize she doesn't need drugs to be happy.
